The app "Documents" referred to above is a good option. It searches inside the documents whether the files are PDF, docx, etc… It sports a clean interface and plenty of remote connection options. And not to mention, it's free with no ads!

We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.

There are several apps matching "Documents" in the App Store. Can you provide some more details (including a link) and also describe how this apps can be used to search through Word documents?
